ROCKFORD — The woman found dead Sunday in the Kishwaukee River — Beverly Janet Gritzmaker, 46 — was most likely the victim of a homicide, Winnebago County Sheriff Deputy Chief Dominic Iasparro said Tuesday.

“She did have some trauma to her body,” the deputy chief said. “I can only categorize it as trauma to her upper body. It’s not a gunshot wound or a stab wound, but trauma to her body.”

Iasparro said he could not say how long Gritzmaker’s body had been in the water, or whether it was a matter of days or months.

Gritzmaker had a minor criminal history.

“We’re speaking to friends, family,” Iasparro said, “(and) looking at her life to determine where she was at.”
